Does the lower the AM radio frequency number goes require night power to be lower or higher?
higher durning the day and lower during the night
Ionosphere
No. Night Vision equipment uses infra-red (IR) light, wavelengths of light longer (lower frequency) than visible light. Infra="below", red, or light below red light in the spectrum. UV stands for ultra (above)-violet, light that is above the violet light spectrum, so higher frequency=shorter wavelength.
at night, when water concentration is higher as more water is retained due to a lower temperature
Yes they are most definately illegal. Deer can not be hunted in the lower 48 at night or when conditions would require night vision. It wouldn't be called hunting if they were.
The Doppler effect causes objects that are moving towards an observer to increase in frequency while those that move away from an observer decrease in frequency. In 1920s and 1930s, Edward Hubble was measuring the Doppler shift of various stars in the night sky, and discovered that there were fa more shifted towards the red spectrum (lower frequency) then the blue spectrum (higher frequency). Hubble concluded from this fact that the universe is constantly expanding outwards, and formulated Hubbles Law to approcimate the rate of universal expansion.
Lower solar input & higher infrared radiation at night could decrease Earth's temperature.
Lower settings give sharper images. Higher settings require less light. Up to ISO: 400 is good because it allow you to take pictures at night, or in darker settings. Higher ISO numbers allow you to take pictures in less light, but increases the risk of more and more "digital noise".
Because the lights that cause them are relatively low. Lower lights ==> longer shadows. Higher lights ==> shorter shadows.
The average night stay at Breckenridge hotels is about $100 dollars. The price could be higher or lower depending on the season. You can find discounts and coupons if you do research.

Prices for hotel stays in Leh can range a great deal. Higher end hotels can cost three hundred plus dollars a night. Lower end accommodations can start at 50 dollars per night.
